I'd noticed there are circular pattern holes between the armrest and the USB ports. Anyone know what this is?
These are multiple tiny hole like a vent. I think it is a temperature sensing opening. Maybe?
temperature sensing was my guess as well (but only a guess)
Isn't the the microphone for the Bluetooth?
Isn't microphone in rear mirror casing?
When my car was delivered the specialist told me they are interior temperature sensors that are only present on newer builds
